Dual-dectector SPECT Gamma camera CardiArc® Scanner

for cardiac scintigraphy

Image Quality When image quality matters - and when doesn’t it matter? - CardiArc® delivers the best available. Resolution - CardiArc® images are the sharpest available - often sharper than PET. Sharper images more clearly identify defect margins. Sharper images better define perfusion in low-flow regions - especially useful when evaluating myocardial viability. Click here for an example. Higher lesion contrast - CardiArc’s higher resolution results in less partial volume effect than other systems. This results in images which more clearly demonstrate the differences in perfusion between myocardial regions. The result - less "gray zone" images. Click here for an example. Less background ’fog’ - Much of the diffuse background activity in lung regions and elsewhere is actually due to a subtle blurring caused by the camera’s response function (wide FWTM). This is present in all cameras using parallel-hole or fan-beam collimators, i.e. all other cameras on the market. This ’fog’ reduces overall image quality by reducing the image’s signal-to-noise ratio. CardiArc’s sharp response function reduces this ’fog’, thereby improving signal-to-noise and target-to-background ratios. Click here for an example. Less motion artifact - The main cause of patient motion is an uncomfortable patient!
